Universal LCD driver for low multiplex rates

7.4 LCD drive mode waveforms

7.4.1 Static drive mode

The static LCD drive mode is used when a single backplane is provided in the LCD. The

backplane (BPn) and segment (Sn) drive waveforms for this mode are shown in Figure 6.

Vstate1(t) = VSn(t)  VBP0(t).

Von(RMS) = VLCD.

Vstate2(t) = V(Sn + 1)(t)  VBP0(t).

Voff(RMS) = 0 V.
